NOTE: This light includes IR (Infrared) LEDs which look dim, they are not faulty LEDs.How does the light work? 26 red LEDs: 26pcs with wavelength 620-630nm, rich sources in red light are more efficient and beneficial for photosynthesis, best for flowering and seed production. 8 blue LEDs: 8pcs with wavelength of 460nm, blue light is more necessary for Chlorophyll and Carotenoid, good for the photosynthesis, best for promoting the stem and leaf. 4 UV LEDs: 4pcs with 380-400nm wavelength,keep plants healthier to grow. 2 IR LEDS: 2pcs with 720-740nm wavelength, play a very important role in flowering and fruiting stages of plants. Specification: LED quantity: 40pcs LED color: red(620-630nm 26pcs)+blue(460nm 8pcs)+UV(380-400nm 4pcs)+IR(720-740nm 2pcs) Power: 20W Input voltage: AC 100-240V Body material: Aluminum (heat dissipation) Net weight: 0.65kg Attentions please: 1.Would be better to keep the distance between the light and plant in 40-60cm. 2.Generally this grow light should be turned on for 5-6 hours every day. 3.Remember to keep enough water for the plants when you use the grow light.

PPUNSON 2018 Unique Upgraded: 1.The lamp adds UV&IR LEDs on the basis of dual head grow light on the current market,covers more wavelengths of light needed by plant's growth. 2.This upgrade version is more bright,lower power consumption and high luminous efficiency. 3.NOTE: The IR (Infrared) LEDs look dim, they are not faulty LEDs.,LEDs COMPOSITION : It totally contains 40 LEDs(26 red LEDs + 8 blue LEDs + 4 UV LEDs + 2 IR LEDs), emits the wavelength of light that can be fully absorbed by plants photosynthesis, best for blooming, fruiting and promoting the leaf.,THE FLEXIBLE, ADJUSTABLE ARMS make you can position the light in any direction. Moreover,the clip is made of metal instead of plastic, which make it more steady than general grow light.
